AbstractThis study extends the heated condensation framework（HCF）presented in Tawfik and Dirmeyer to include variables for describing the conventional background state of the atmosphere used to quantify the contribution of atmosphere to conventional initiation within the context of land-aerosol coupling.特别是，全套HCF变量的能力，1）量化的潜热和显热的对流启动所需的能量，2）识别从增湿优势的过渡到边界层增长的优势，3）识别本地起源的对流，和4）比较模型和观测，直接突出的对流状态的偏差，证明。这些能力说明了一个晴朗的天空和对流活跃的一天，在大气辐射测量计划南部大平原中心站使用的意见，快速更新周期（RUC）的业务模式，和北美区域再分析（NARR）。晴空万里的一天
AbstractThis study extends the heated condensation framework (HCF) presented in Tawfik and Dirmeyer to include variables for describing the convective background state of the atmosphere used to quantify the contribution of the atmosphere to convective initiation within the context of land–atmosphere coupling. In particular, the ability for the full suite of HCF variables to 1) quantify the amount of latent and sensible heat energy necessary for convective initiation, 2) identify the transition from moistening advantage to boundary layer growth advantage, 3) identify locally originating convection, and 4) compare models and observations, directly highlighting biases in the convective state, is demonstrated. These capabilities are illustrated for a clear-sky and convectively active day over the Atmospheric Radiation Measurement Program Southern Great Plains central station using observations, the Rapid Update Cycle (RUC) operational model, and the North American Regional Reanalysis (NARR).
